Short version of my email to Wim:
It looks like a known bug - IPSEC code seems to ignore dev->hard_header_len = 10 requirement for PVC devices and passes skbs which have less than 10 bytes of header space. Not sure how does it work with Ethernet which requires 14 bytes, though. It might be a good idea to investigate.
I wonder if the FR behavior is correct - i.e. is it OK to set dev->hard_header_len = 10 and expect that all skbs passed to dev->hard_start_xmit() will have at least 10 bytes of space before the data?
Does the situation depend on dev->hard_header being non-NULL? -- Krzysztof Halasa, B*FH - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
